Description
Technical field
The utility model relates to Aluminium Electrolysis apparatus field, is specially a kind of hinge-type anode rod tightness system, is mainly used for the sealing of electrolyzer, makes electrolyzer improve the measure of utilization rate of electrical.
Background technology
Sodium aluminum fluoride-alumina molten salt electrolysis method that aluminium electrolytic industry is taked, direct current passes into (the wherein composition such as salic, Calcium Fluoride (Fluorspan), magnesium fluoride) electrolyzer that is loaded with cryolite melts, on anode and negative electrode, there is electrochemical reaction, on negative electrode, obtain product aluminium liquid, on anode, produce CO2 and CO gas, the process flow sheet of electrolysis of aluminum as shown in Figure 3.
A chemical equation of electrolysis of aluminum is:
Al
2O
3+1.5C===2Al+1.5CO
2
As can be seen here, electrolyzer is the core of whole Aluminium Electrolysis, is main equipment, and the equipment quality of electrolyzer, plays a part crucial to the utilization of electrolyzer energy.
Aluminium industrial production status of energy consumption is now, approximately 3.95-4.15V of the average voltage of electrolyzer, current efficiency 90-94%, the ton aluminum direct current consumes 12600-13100kw.h, ton aluminium ingot Integrated Exchange 13600-15000kw.h, the overall utilization 44-47% of energy, in addition 53-56% all dispelled the heat from the surrounding of electrolyzer, in order to reduce the heat dissipation capacity of electrolyzer, just must carry out insulation and the sealing of electrolyzer.The sealing of electrolyzer mainly contains the sealing of groove cover, anode rod sealing, attacking head sealing.
The current continuous progress along with electrolysis designing technique, design and material to electrolyzer are all optimized, and adopt the design concept of thermal-insulating type electrolyzer, have strengthened insulation and sealing to electrolyzer, the capacity usage ratio of electrolyzer is also improved, and can reach more than 50%.
The sealing of anode electrolytic cell guide rod is to fix the heat-resisting woven asbesto of a slice on three limits of guide rod corresponding groove eyebrow opening, and in absence about damaging, sealing effectiveness is fine.But electrolyzer all will be changed anode operation every day, everywhere guide rod seals each anode change cycle will be once, anode rod has repeatedly action up and down at this mouthful of place, damage is caused to the sealing at this place in capital, therefore the bad seals rate at this place is very high, some 1-2 cycle is just bad, and the longest also only has 3-4 cycle.Sealing is repaired and is changed and is all difficult to operation.
The sealing of visible guide rod has determined the sealing of whole groove, if electrolyzer exhaust blower scarce capacity, negative pressure is less, and the flue gas of electrolyzer will be emerged from sealing so, affects the environment of factory building, and calorific loss also increases simultaneously, causes energy consumption to rise.If negative pressure is large, because guide rod sealing is poor, the freezing air of outside will enter electrolyzer from sealing, and the heat absorbing in electrolyzer is finally drained from smoke exhaust pipe, also causes capacity utilization ratio to reduce, and increases the power consumption of exhaust blower simultaneously.
Utility model content
Fragile in order to overcome existing anode rod sealing, cause the deficiency that power loss is large, the utility model aims to provide a kind of hinge-type anode rod tightness system, and sealing device makes electrolyzer can have a good tightness system, thereby reduces power loss.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of hinge-type anode rod tightness system, its constructional feature is, comprises two opposed sealing plates, each sealing plate inner side is all fixed with sealing ply; Each sealing plate outside be respectively provided with a rotating shaft, described sealing plate is contained in corresponding rotating shaft and can the upset of phase countershaft; Between described thermal-insulating sealing layer and electrolyzer eyebrow plate, can form the cavity of anode rod shape of cross section.
Thus, described two sealing plates and corresponding sealing ply close up in the time of electrolytic reaction and entirety is in shaped door, and sealing ply and anode rod closure; Described two sealing plates and corresponding sealing ply are in the time changing anode rod, and described sealing plate and corresponding sealing ply separate with described anode rod.
Be below the technical scheme of further improvement of the utility model:
As a kind of concrete rotational structure form, described anode rod is each side provided with a pipe being contained on upper part of the electrolytic cell cover plate, a L shaped rotating shaft is housed on each pipe, and one end of this rotating shaft is placed in corresponding pipe, and the other end is fixed on the L shaped sealing plate of corresponding side.
Described sealing plate is L-shaped, and two sealing plates can form the portal structures with sealing ply parcel three sides of anode rod while rotation in opposite directions.Thus, this heat-resisting woven asbesto and electrolyzer eyebrow plate form the cavity of anode rod shape of cross section, and in the time of the equal anode guide rod upset of sealing plate, sealing plate, heat-resisting woven asbesto and electrolyzer eyebrow plate are jointly incubated and seal electrolyzer.
Preferably, described sealing ply is heat-resisting woven asbesto.
By said structure, according to the size of electrolyzer eyebrow plate place anode rod opening part, design a pair of guide rod sealing plate of singly opening, after two sealing plates close up, be just in time the same shape of electrolyzer eyebrow plate opening, heat-resisting woven asbesto is installed on sealing plate, then weld one the 90 bending 14mm round steel of degree, on groove eyebrow, weld two 1/4 cun of steel pipes, finally by sealing plate round steel insert in steel pipe.While changing anode, sealing plate is opened, after change poles and EO, then sealing plate is closed up.Pole changing anode rod and sealing plate can not come in contact, and can not cause damage to tightness system, and be the more than 10 times of former sealing the work-ing life of sealing.
Compared with prior art, the beneficial effects of the utility model are:
1. movable device design has been carried out in pair electrolyzer guide rod sealing, is easy to processing and changes.
2. this device adopts hinge-type, while changing anode, sealing plate is opened, and after change poles and EO, then sealing plate is closed up.Pole changing anode rod can not come in contact with device, can not cause damage to tightness system.
The work-ing life of sealing device very long, as long as heat-resisting woven asbesto is not bad, just need not change.
4. after applying, to the good sealing effect of electrolyzer, prevented that flue gas from emerging on electrolyzer, also prevented that freezing air from entering electrolyzer, exhaust blower also can move under the most energy-conservation pattern, has energy-saving and cost-reducing effect.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
